To all u'hom t may Concern:

Be it known that we. FRANCIS H. BROWN ind',O'i"ro Rizesnn, both citizens of the hited States, residing in the city and -eounty of Philadelphia, State of Pennsylvania. have invented a new and useful Regulating and Controlling Device, of which the. following is a specification. i

Our invention consists of a novel construe tion4 of regulating -and controlling device wherein a novel type of diaphragm is eniployed which is operatively connected to other mechanism in a novel manner in or- 'der to Vactuate the saine or to be actuated thereby. It further consists of a novel regulating'and controlling device, wherein a Inotor is controlled in a novel manner b v means of a regulaton' said motor being adapted to control in a novel manner, a valve connection.

It further consists of a novel manner oi and construction for connecting the different parts in operative relation `with respect to 4each other.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating our invention, we have shown in the drawings an ein bodiinent thereof lwhich is at present preferred by us, since the saine will give in practice satisfactory and reliable results, although it is to be understood that the various4 instrumentalities of which our iiivention'eonsists can be variouslyI arranged and organized and that our invention is not limited to the precise arrangement and orH ganization of these instrumentalities as herein `shown and described.

figures ,our novel reglilating and controlling device as being employed Yto control ina. novel, manner, a novel niotor and valve mechanism. V

Re'ferring'iirst more 4particularly to Figs.

1 and 2, it will he seen that our novel typeV of regulating device is adapted to actunte easing,` and in this embodiment the easin members 43 and 44 andgsiconduitf45- is provided leadiiig to the el Ulilxi .4.6'0n'oneside ofthe diaphragm. y.

47 designates a valve? leading from the chamber of the diaphragm, which latter is provided withgsuitable drainage Ineens.` 49 desig.

lfing into the chamber 48 on the opposite sdeQ the controlling device seen in Fig. 15 but device and as will be hereinv 9, 10, and 11', it will be noticed that the block 18 is provided with a laterally extendin Fig. 9.

54 designates a lever, one end of which is secured to the lever 51, the other end thereof being fulcrumed at 55, it being understood that the block 18, rings 19 and spacing washer 17, are suitably apertured at this print in order to permit the free movement of the lever 54.

56 designates a lever having one end connected with the lever 51. the other end thereof extending exterior of the casing 43 and having secured thereto an elbow lever 57, it being understood that the block 18, rings 19, andv spacing washer 17 are suitably apertiired to-permit the rocking movement of lthe lever 56.

58 designates a bell crank lever fulcrumed at 59 and having one arm provided with a bracket 60 with which is adapted to co-act an adjusting screw 61, the latter also coacting with the bracket 62 carried by one end f the arm 57 secured to the lever 56.

Referring now more particularly to Fig. 11, 63 designates a limiting member which, in the present instance, consists of a screw or pin having threaded engagement with the spacing washer 17 and having its inner ends provided with heads of different diameters,

as indicated at 64, 65, 66, 67 and 68, it neing understood that these heads are located in a recess which extends through the rings 19 and also into the block 18, the purpose of the graduations 6i, 65, 66, 67 and 68 on the pin 63 is to permit the spacing rings 19 and the spacing member.18. to

freely move in unison with the ilexible members 15 and 16 of the diaphragm, it being seen that the ring nearest to the washer 17 has the least amount of movement, while the,-

ring nearest to the block 18 is capable of the greatest amount of relative movement.

T he arm of the bell crank lever 58 which carries the crank 60 is provided with an adjustable counterweightV 69 which takes up any, lost motion between the' parts. The opposite end of the bell crank lever 58 has pivoted thereto at 70a bracket 71 having arms 72 which carry a red 73 which is adapted to be engaged by the fork 74 carried bv one end o? a bell crank lever V75 rule-ruined at 76 in a bracket T7, which latter is secured to the hollow shaft 78 of a piston 79 located in acasiiig 80 suitably carried by the extension 81 of the lower casing member of the device.

L. order to accurately control the amount of movement oin the piston 79 relatively to theX-"ariation in fluid ressure on thediaphragm, we provide the lower end ot the lever 71 withl the gear teeth 171 which coact with the manually controlled worm 172.

.82 designates a. rod carried by the bracket 77 tand adapted to travel in an aperture 83 to prevent rotation of the bracket 77 during its reciprocations. One end of the bell crank packing nut 86 carried by said bracket, said Valve stem also passin through the motor or piston shaft 78, which is adaptedto reciprocate in the casing 80, which latter is provided with a suitable fluid inlet 87.

In order that the operation of the motor may be readily understood, we will now describe the manner in which the fluid passes to o erate the motor.

'1' 'e piston 79 is provided with a reduced diameter 88, thereby forming a chamber which is always filled with the motive fluid which passes thrcugh the inlet ports 89 to the chamber formed by the heads 90 and 91 on thevalve casirg 92 which is fixed in the bore 93 of the piston 79.

94 designates the inlet iii the motor casing which is always open to the motive fluid supply, so that when the valve heads 95 and 96 are in the position seen in Fig. '13, the motive fluid will be prevented from operating the piston. i

Assuming that the valve stem 85 moves downwardly, then the motive fluid may 'pass through the port 95 around the reduced neck 97 ofthe valve, thence through the port 98 and through the passages 99 in rear ofthe piston 79, and causes the latter to move downwardly, the motive fluid within the motor -beihg'permitted to escape through the passages 100, thence through ports 101 and through the end. of' the valve easing 92, thence through the motor shaft 78 and through the passage 102 in the bracket 103, with which communicates a conduit 10i leading to a suitableA point of discharge.

Assuming that the valve stem 85 is moved upwardly, then `the motive fluid will enter through the inlet 94, passing around the neck 97 of the valve, thence through the port 105 through passages 100 beneath the piston 79 to cause the piston to move upwardly, thereby carrying with it the bracket 77.

.As the piston 79 moves upwardly the fluid in rear of the piston may escape through the passages 99, the ports 106, tbrcugh the end of the valve bushing and thence through port 1'07, passage 108 and port v109 tothe hollowv motor shaft 7S, and thence through the passage 102 andthrough the conduit 104.

ros

is fulcrnmed lat 112 in an arm carried byv the lower casing member of the device. lThe opposite end of said lever 111 is suitably forked and adapted to engage a pin 113 carried by a valve stem 114 which is connected with' a. cup-shaped valve 115 mounted in a casing 116 carried by the flange 81 of the casing 41,-whereby the valve 115 is capable 5 of botha reciprocating and a rotary motion.

The valve .casing 116 provided with an inlet 117 which communicates with an. annular passage 118 provided with a plurality of ports 119 communicating with the valve x clamber 120. The valve 115 is provided with ports 121 which are adapted to register it certain times with the ports 119 as will later be more fully described, so that the fluid may pass through the port 117, thence into the chamber 118, through the ports 119 and ports 121 into.a chamber 120 and thencethrough the outlet 122` The novel type of mechanism which we ha ve just described is adapted to receive not i. only a reciprocating movement but the rota- "0 a bracket' 131 adapted to be secured to a casing 116.

132 designates a worm mounted in the bracket 131 adapted to co-act with the teeth 133 on the lower end of the arm 128, whereby said arm may be angularly inclined in order to cause any desired rotation of the valve stem 114, and thereby control .the amount of opening of the ports 121 and 119.

The oeration of my invention will now be readi y apparent and is as follows :-V

Referring to the construction seen in Figs.- 1 to 6 inclusive, we have shown a conv struction wherein the movement of the diaphragm is conmiunicatcd exl'eriorly o'i the casing, and 1n this construction the fluid enters the. conduit 15, and assuming that the valve in the Ji )e 17 is o )en the fluid -ma l l l s .Y

pass into the chamber 48, so thatrthc pres! sure in the chambers 4G andv 48 oli opposite sides of the. diaphragm will be equalized, it

being understoodthat an air cushion is loi-ined in the bell float 49 or its equivalent.

The-valve in the pipe 47 will now be closed, so that a desired or predetermined ,55 pressure will be maintained in the chamber 48 and variablelpressine will be maintained ih the chamber '46, since the conduit 45 will 'be connected with a source of supply which 'lislconstantly varying.

,Assuming now that the 'pressure in the il'hiambe'r 46 increases, it will be apparent `l`that that diaphragm will move downwardly and owing to the manner in which the levers 5151 and56 are mounted in the dia- 5 phragln, they will move downwardly in unison therewith, so that a downward pull will be imparted to the bell crank lever 58, thereby causing the u pper end thereof to` move downwardly@whereupon the bracket 71 will be moved outwardly, so that the bell crank lever 75`will beractuated and cause` the valve stem 85 to move downwardly.l

When the valve stem 85 moves downwardly, n'iotive'tluid may enter through the po`rt 87, thence. to the ports 89 and 94 through the port 98, as best understood by reference to Figs. 1.3 and 16, through the passages 99 above the Jislon 79, and cause the piston 79 to move downwardly, thereby causing the bracket 103 to move downwardly. As the bracket 103 is moved downwardly, the lever 111 will be rocked on its tulcrum 112, thereby causing the valve stem 114 to be raised, and owing to the manner in which the upper end of the valve stem coacts with the lever 121i, it will be apparent,l that in unison with the reciprocating of the valve siem 114, that the valve 115 carried thereby will be rotated, thereby causing the valve 115 lo -open and permit fluid to pass through the port 117, through the ports 121 and 124. and thence through the discharge port 122 to a desired point of utilization.

The amount of rotation imparted to the .i

valve 115 is regulated as desired by manipulating the` worin- 133, whereby thev angle which thelever 126 assumes with respect to the longitudinal axis of the valve stem 114 may belvaried as desired. The amount of movement imparted to the piston 79 may be controlled as desired by manipulating the worm ,172, which as will be apparent, varies the throw of the valve-stem 85.

Owing to the provision of the novel means for regulatingT the throw of the valve, the movement ole the piston 70 may be accurately regulated, so that any desired movement of the piston may be produced for a, Y

preslelermined i-'a-rialion in pressure in the chamber 4U ou one side of the diaphragm.

When the diaphragm moves upwardly, it will be apparent that the motor wil be actuated in a reverse directiontherebcausing reverse action to that above described of the valve 115 and itsV adjuncts. i

It will he apparent that when the worin 172 is actuatedJthejlever 71 will move on its pivot so that.' the 'amount of movement .imparted to lhepist-on 79 may be varied as desired, it being `apparent that we `employ a somewhat' similar construction` as seen in Fig. 2, t'or varying the amount of rotary movemem imparted to thevalve 115.

lt will be aiiparen't. that the novel construction ol' diaphragm hereinY disclosedforms an extended flexible joint which enahlesl the same to'Abe employed in connection with much higher pressures hanhas hereto` fore been deemed possible, nd it has been found in actual practice that owing to theI formation of this extended fiexible joint a verydelicate and accurate movement of the flexible member takes place, and several hundred pounds pressure may be employed without injury to the diaphragm or destroying in any manner the sensibility of the flexible member. l

In so far as we are aware, we are the first to provide means for varying the stroke of the valve to vary the length of stroke-of the piston either alone or in combination with a controlling valve, ,the action of which regulating and controlling device which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While We have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactoryand reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the` `invention or sacrificing any of its advantages.
